Service tax on freight (reverse charge query)

Dear Sir,

We are paying service tax under reverse charge mechanism. Generally GTA doesnt charge service tax in their invoice. We pay to them their fee and deposits service tax @ 3.09%

We have received one invoice in which service tax is charged by GTA in their invoice.
Invoice is as follows.

Fee                 = Rs 1000.00
Service Tax @ 3.09% = Rs   30.90
Total               = Rs. 1030.90

We have paid them Rs. 1030.90.

Do we have liability to pay service tax under reverse charge even we have paid to GTA.?
